The Spurs look somewhat like a combination of both. I think Parker needs rest and I don't know what the Leonard's deal is this season. But from what I've seen, it seems like the Spurs coast in the first 3 quarters and try to wake up and win games in the fourth. It has worked a few times but when you let some teams stay in it like this they get confident and you have scrubs like Shumpert going for career highs. They play extremely complacent most of the time except for the end of quarters/4th quarter. is kind of annoying, it's why the 2nd unit comes in and wrecks so often because they, unlike the starters, play with more intensity. It's no coincidence that the Spurs go on runs routinely to end quarters since the 2nd unit is usually out there to end a quarter.
Spurs starting lineup has been bad this year, and it makes no sense, so I'm leaning towards coasting. But they also haven't played up to par at all against the top teams. It's hard to say. I'll reserve judgment til after the ASB. Spurs routinely start off slow and gear up towards the end of the season, we can only hope they are trying to pace themselves after a long season/playoffs/grueling finals last year.
